During knee joint tibial insert surgery, the surgeon will make an incision in the knee and remove the damaged portion of the tibial plateau. The surgeon will then prepare the bone to receive the tibial insert implant. The tibial insert is a plastic spacer that fits between the tibial plateau and the femoral component.The surgeon will use specialized tools to precisely fit the tibial insert into the tibial plateau. The fit must be precise to ensure the knee joint operates smoothly and there is no excessive friction between the insert and the femoral component.Once the tibial insert is in place, the surgeon will close the incision and the patient will begin the recovery process. As with femoral component surgery, patients will typically need to participate in psical therapy exercises to help strengthen the knee and promote healing. After a few months of rehabilitation, patients can normally expect the knee to feel much better and have improved functionality. However, it is important to follow any post-operative instructions provided by the surgeon to ensure optimal healing and recovery.
